Question

Given : velocity = 32km/jam
Massa = 60 kg

pertanyaan : energi kinetik = .... ?

Answer 1

V = 32 km/jam = 8,89 m/s
m = 60 kg

Ek = ?

Ek = 1/2 m v²
Ek = 1/2 x 60 x (8,89)²
Ek = 2370,963 J

Answer 2

Dik :
V = 32 km/jam
m = 60 kg
dit : Ek ?

V = (32x1000)/3.600
   = 32.000/3.600
   = 8,89 m/s

Ek = 1/2 x m x v²
     = 1/2 x 60 x 8,89²
     = 1/2 x 60 x 70,002
     = 1/2 x 60 x 70
     = 2100 J
